ive got a stutter...

[gi_jackii]

:shrug:if any of you guru's can help it would be great... ive got a stutter when im cruzing at a constant speed and cant for the life of me figure out what it is. it doesnt do it at WOT, just at a consistant rpm. it feels almost like a miss, but a REALLY long one. ive changed the fuel filter, cleaned the MAF, and am going to go ahead and run sea foam through it tomorrow/ change the plugs and oil. anyone have any suggestions on what it could b? (04 mustang GT, manual trans) thanks in advance

have you checked the pcv valve? Mine did that (not a long one but a short one) and when I changed it out it went away

That's nothing.
I used to know a guy who worked at an AM radio station.
When he was talking, he lost his voice when we went under a bridge.

Seriously, it sounds like an ignition coil. (COP)
Also check the spark plugs.

P.S. finally found out its the fuel pump. wasnt throwing a code, but wasnt holding sending pressure either...
